Hi,
Yes, exactly. The 2nd MIDI Port will control channels 9-16.
Right.

Do you guys have any idea how i can find a complete reference of the Mackie protocol? I know it is propietary, but i need to know to implement it in the electronics (arduino). or i can spend a day to sniff all messages with MIDI-OX but i guess somebody already did that job? .
This web page helped me a lot. But there is no information, how the display is handled. For this I made my own research.
